Which is what we have, and have had, for a very, very long time.

I have not noticed that wealthy people care more about the environment than poor people. It seems to me that it tends to be the other way around.

Bicycles are already produced at scale and have been for longer than cars have existed.
Huh? Do you mean that deregulation is the best way to solve this?
The cheapest options for end consumers will almost always be the things that scale the most: race-to-the-bottom, and exploiting the commons as much as possible. While I agree that regulations are gamed, to suggest deregulation as the key solution means disregarding why we have regulation at all.
Personally, I think this isn't an either-or kind of thing. I, and plenty of people I know, have both a bike and a car. They use the bike for relatively short trips, shopping, etc., and the car for everything else. As it turns out, the vast majority of driving people do are the sorts of trips that can be done easily (and more quickly) on a bike anyway.
People who simply cannot bike for whatever reason will continue to drive. That's fine. But we still need to shift the balance so that it's easier and safer for people to bike, even if it makes using a car slightly less convenient.
